Encountering platform mismatch issues with the slim variants of the Python Docker images.

This issue seems to be specific to the slim variants of the Python images. The manifest for arm32v7/python:3.12-slim includes platforms linux/arm/v8 and unknown/unknown, causing a mismatch during the build process.
